Copper Fox Metals Inc (TSX-V:CUU, OTCQX:CPFXF) has provided an update on its 100%-owned Eaglehead polymetallic porphyry copper project approximately 50 kilometers (km) east of Dease Lake in British Columbia.
"The 2022 program eliminated ‘legacy data issues’ with the project database, expanded the area of surface copper mineralization and revised the geology of the southwest portion of the Eaglehead Intrusive,” Elmer B. Stewart, president and CEO of Copper Fox said in a statement.
“Eliminating legacy data issues and determining the extent of the mineralized envelope for the mineralized zones is a prerequisite to establishing a database that potentially could be used to initiate a resource estimate. The field mapping program, age dating and geological modelling provided a better understanding of the lithologic control and distribution of the mineralization in the southwest portion of the Eaglehead Intrusive and an updated geological model for the Bornite and East zones," he added.

The update, through its wholly-owned subsidiary Northern Fox Copper Inc, highlighted that notice of work has been received from the British Columbia Ministry of Energy, Mines and Low Carbon Innovation.
The Eaglehead project is in the prolific Quesnellia terrane in British Columbia and covers a large portion (16,492.62 hectares) of the Lower Jurassic age (+/-195Ma), Eaglehead Intrusive.
Other highlights include:
- The re-log and sampling program returned additional intervals of significant copper mineralization.
- The geological modelling of the mineralized zones and surface mapping program has better informed the controls on mineralization and revised the geology of the southwest portion of the Eaglehead Intrusive.
- The water quality sampling shows no appreciable changes in water quality over the season.
Analytical Results
The company said geological modelling included reviewing the lithologies, alteration and mineralization in 34 historical drillholes within the Camp, Pass, Bornite and East zones. The work identified previously unsampled intervals of copper mineralization in 11 drillholes, the company said.
Sampling of these intervals established the tenor of the copper and associated mineralization and, in several drillholes, extended the limits of the mineralized envelope in these holes.
Geology
The 2022 surface mapping program combined with the subsurface modelling of the lithologies within the Bornite and East mineralized zones resulted in updating the distribution of the lithologies within the southwest portion of the Eaglehead Intrusive. Hornblende quartz Diorite is the oldest unit within the Eaglehead Intrusive. The Quartz porphyry is granodiorite in composition and is the most abundant unit with the Eaglehead Intrusive. The youngest unit is granodioritic in composition and is located between the Quartz porphyry and the Hornblende quartz Diorite. The copper-molybdenum-gold-silver mineralization is primarily hosted in the granodiorite. Late-stage aplite, quartz feldspar porphyry and mafic dikes also occur with the mineralized zones and in outcrop.
Copper Fox focuses on copper exploration and development in Canada and the US. The principal assets of Copper Fox and its wholly owned Canadian and United States subsidiaries are the 100% ownership of the Van Dyke oxide copper project located in Miami, Arizona and the 25% interest in the Schaft Creek Joint Venture with Teck Resources Limited on the Schaft Creek copper-gold-molybdenum-silver project located in north-western British Columbia.
